The company producing pre-packaged https://cookwith2chicks.com/ Oreo products changed its recipe in the 1990s to exclude lard (pig fat) from its filling to provide more healthy Oreo varieties. They first replaced it with hydrogenated vegetable oil and then non-hydrogenated one. In 2013, they decided not to include whey protein in their cookies to free them from animal-based ingredients.
